The time course of figure-ground reversal

The time course of figure-ground reversal.

We report the results from five experiments employing a modified version of the short-term visual matching (STVM) method introduced by Driver and Baylis (1996). In STVM, participants see a study display with ambiguous figure-ground relations. After the study display, participants have to decide which of two shapes in a match display was seen before in the study display. STVM has been used by Ve...

Figure-Ground Reversal in Linguistic Humour

Visual Attention Model in Figure-Ground Reversal Perception

In figure-ground reversal perception for ambiguous figures, figure-ground relationship reverses depending on the position and the range of our attention. Our attention also changes depending on figural features. We propose a neural network model that explains a dynamic process concerning figure-ground perception and visual attention. Our model consists of two mechanisms: (i) one determines figu...

Shape recognition contributions to figure-ground reversal: which route counts?

Observers viewed upright and inverted versions of figure-ground stimuli, in which Gestalt variables specified that the center was figure. In upright versions, the surround was high in denotivity, in that most viewers agreed it depicted the same shape; in inverted versions, the surround was low in denotivity. The surround was maintained as figure longer and was more likely to be obtained as figu...

Real-Time Maintenance of Figure-Ground Segmentation

An approach to figure-ground segmentation based on a 2dimensional histogram in feature space is presented. The histogram is then analyzed with a peak-finding algorithm designed with real-time performance in mind. The most significant peaks in the histogram are backprojected to the image to produce an object mask. The method is applied to segmentation based on a 2-D color space and also on a com...
